Update: I have fixed the problem. The short answer is that I needed to re-flash with the contents of SL6000L-US-1.12.zip.

Googling for this will return several download sources. I thought I had done this already, but it turns out that the file I used, 20040217SL6V112.zip is not the same. Must be for a different TOSA model. At any rate, if you suffer from similar problems, just download the SL6000L-US-1.12.zip and put the contents on a compact flash card that has been formatted to FAT16 (NOT FAT32!!!), insert it into the slot with power turned off, hold D+P to enter the Maintenance/Diagnostic Menu, and select CF Update.


Original Message:
I'm a little concerned that the last post in this section was back in March. Hopefully there are enough of us Tosa owners out there that someone knows the answer to this problem.

I just bought an SL-6000L and SL-C31000. Neither one would boot when I powered them up. The C3100 solution required re-flashing the NAND, and re-partitioning the internal HDD. The SL-6000 seems to be a little more complicated.

I am suspecting that the battery had been totally discharged, and that this caused a problem where the Z thinks it is fully charged, and thus will not allow the battery to charge. I was able initially to get the maintenance menu up (D+P, and D+M), but then I think the battery lost too much charge, and I was not able to get in any more.

I took a lab power supply and charged up the battery a bit externally, and I'm now able to access the Diagnostic Menus once again, however I can still not boot the thing using the power button.

Here are the symptoms:
1. When plugged in to AC adapter directly or through the dock, amber charging light does not turn on.
2. Pressing the Power On button causes the Mail and Charge LEDs to faintly flash momentarily, but the unit does not power on, and the screen does not react in any way.
3. In order to enter Maintenance (D+M) or Diagnostic (D+P) modes, the battery must be removed, the backup battery switched toggled, battery re-inserted, and then reset while pressing the D+M or D+P keys.
4. Re-flashing NAND using the Q+T+reset seems to work (except that it does not boot afterward, of course)

Hopefully someone out there knows the answer!

There's some Tosa love still in the universe! There are some OE people working on the Tosa kernel...slowly but surely. If the kernel gets stabilized, we can expect to run a modern OS (Android, Linux / Enlightenment, Zubuntu, etc...) on the Tosa.

Where did you get that copy of the ROM? I'm not sure if that's the one provided by Sharp or not.
